What? Just cut the little tab on the sylus with nail clippers. No need to hack the cart.
Strangely, I thought I would try the next one up, the 300SE with an Ortofon OM Super cart, and unlike the 200NE + OM10, it fits perfectly, no need for surgery!
Where might I find one of these?

There has to be another great deal out there.
Me too. Oh, well---.Damn I was hoping this thread was going to report that this sale was back.
I bought a few and still like them for 'P' mounts. A steal at $20 either version, $100 not so much. I'm into MC and strain gauge carts these days so they don't get much vinyl time.
